VERTICAL-SPINDLE LUBRICATION.

reoaaoa.

To all whom t may concer/n.:

Be it known that I, CARLO SELLA, citizen of Italy, residing at Turin,Italy, have invented new and useful Improvements in Vertical-SpindleLubrication, of which the following is a specification.

This invention relates to an apparatus for automatically lubricating,during rotation, verticalaxles of any kind, and particularly Spinning,twisting and preparation spindles.

In the accompanying drawings showing several arrangements of theapparatus, Figure 1 is an elevational view part being shown in sectionfor the sake of clearness; Fig. 2 is a transverse sectional view takenthrough the box; Fig. 3 is a plan View; Figs. 4t, 5 and 6 are viewssimilar to Figs. 1, 2 and 8 showing a modified form of the apparatus;Figs. 7 and 7b are detail views; Figs. S, 9 and 10 are views similar toFigs. 1, 2 and 3 showing another modification; Figs. 11, 12 and 13 areviews similar' to Figs. 1, 2 and 3 showing another modification.

As shown in Figs. 1, 2 and 3 the apparatus comprises a reservoir orVwell S, and boxes 7) within which the vertical axle is rotatablymounted. rIhe box b is provided with an opening f which exposes aportion of the surface of the spindles or axles. A cotton wick extendsin the reservoir S and also engages the exposed portion of the axlethereby continually lubricating the said axle or spindle.

In the Figs. 1, 2, 3 the boxes b are placed in circular chambers Sformed in the reservoir S and are kept in place by nuts d. The chambers`are provided at spaced intervals, thus spacing the oil compartments inseries therewith, and the wicks extend through openings S in the wallsof the chambers and through the openings f of the boxes, the boxes beingprovided or formed with flanges at their upper ends snugly fitting thechambers and lying flush with the top of the reservoir or well. In orderto prevent leakage from the reservoir a leather packing c is provided.For the introduction of the oil and the discharge of air holes .areformed in the upper portion of the reservoir, which is also fitted withlugs to mount the same on the machine benches.

In the arrangement shown by Figs. 4, 5, 6, 7, each box has its ownreservoir and is supported by a plate p, the reservoirs being spacedapart and forming chambers for receiving the boxes therein. The box has.a

slightly different shape from the preceding form, being provided with aspherical bearing which seats in a corresponding cavity in the reservoirso that an air tight joint is formed. Each box is held in placebv aspring m which is kept under tension by a( ring n provided with lugs f/engaging notches e, the springs exerting downward tension between thereservoir and rings so as to hold the boxes firmly in their seats. Theupper part of the box is recessed at z' to receive the cotton wick andlubricant and the opening f communicates with the recess. Acorresponding flange is also provided at the top of each box.

In Figs. S, 9, 10, the box is not formed in one piece, but is providedwith a removable upper head or flange t which can be screwed into thebody portion of the box keeping in place a thin metallic ring Zwhichsurrounds the cotton.

In Figs. 11, 12, 13, the reservoir comprises a single receptacle inwhich box supports g are fixed by means of nuts el engaging reduced andexteriorly threaded lower ends of the supports and bindingly engagingorholding the reservoir. The supports have spherical seats to receivethe boxes which have corresponding spherical bases. By this constructionslight movement is possible for the adjustment of the bearing box in itsposition and, besides, they are perfectly tight. The heads or flanges oof the boxes are also removable, and screwed to the body H portions soas to keep in its place the ring Z which surrounds the cotton wick Z2,and openings e are provided to allow the cotton wick to engage thespindle. The introduction of oil is through the hole 1 which is closedby a button on the spring e which is pivotally mounted on the reservoir.The springs m are kept in position by elastic forks engaging circulargrooves in the box, or by a joint asbefore described. rI`he reservoir ortank may be secured to the machine by means of lugs.

What I claim is 1. In a vertical spindle or axle lubricator, a reservoiradapted to contain oil, said reservoir having a top portion, a. boxadapted to receive a spindle and having a head at its upper end flushwith the top portion, said box being provided with an opening in itswall, means to hold said box under downward tension, and a wickextending into said reservoir and through said opening where? by it willengage the spindle to supply lubricant thereto.

2. In a'vertical spindle lubricator, a sup` port having attachingportions and formed at spaced intervals with compartments providingreservoirs, boxes lin said compartments and having spindle receivingbearings, said boxes having flanges projecting outwardly from theirupper ends to snugly engage the interior walls of the compart- 'ments,said boxes projecting downwardly through and from the compartments,means mounted on said downwardly projecting portions to secure Saidboxes in position, said boxes having openings therethrough and means forsupplying lubricant from the reservoirs through the openings to thespindles. i

3. In ar device of the character described, agreservoir adapted tocontain oil, a box adapted to receive a spindle, means for anchoringsaid reservoir, said box being provided with a spherical bearing in saidreservoir, a spherical seat engaged by said bearing, said box beingprovided with an opening in its wall, `and a wick extending into saidreservoir and through said opening whereby it will engage the spindle tosupply lubricant thereto.
